Streamlining KYC with Blockchain - The Future of Identity Verification

Financial institutions rely heavily on Know Your Customer (KYC) processes to combat money laundering. The global e-KYC market is booming, expected to reach a staggering $1.57 billion by 2027, reflecting the industry’s focus on KYC.

However, despite these investments, traditional KYC processes remain riddled with inefficiencies. They often prioritize data collection, leaving limited resources for crucial tasks like risk assessment and ongoing monitoring. This imbalance, coupled with the tedious and repetitive nature of KYC, creates a frustrating experience for both institutions and customers.

Enter blockchain technology, a potential game-changer for KYC. This blog dives deep into blockchain KYC, exploring its significance, functionalities, and implementation. We’ll uncover how blockchain can transform and secure KYC processes, addressing current challenges and paving the way for a smoother, more customer-centric approach.

Traditional KYC

Traditional KYC refers to the standard procedure used by financial institutions and other organizations to verify the identity of their clients or customers. The primary goal of traditional KYC is to ensure that individuals engaging in financial transactions or accessing certain services are who they claim to be, thereby mitigating the risk of fraud, money laundering, and other illicit activities.

The traditional KYC process typically involves three main elements:

1. ID Verification (IDV)

This includes verifying the identity of an individual through the submission of original documents, scanned copies, or photographs. The documents may include passports, birth certificates, social security cards, or driver’s licenses. The verification process may involve a superficial check, and in some cases, documents are cross-referenced with databases, such as credit history databases.

2. Client Identification Program (CIP)

Organizations implement various means to check documents against state and corporate blacklists. The methods can vary, ranging from analyzing documents to utilizing fingerprints or facial scans. There is no standardized approach, and organizations choose the means of control based on their capabilities and jurisdictional requirements.

3. Video Identification 

Some traditional KYC processes incorporate video identification methods, such as video calls through platforms like Zoom, Skype, etc. This is an attempt to address the challenge of remote identification.

One of the key drawbacks of traditional KYC is its decentralized nature, where each organization or government agency independently conducts identity verification. This leads to redundancy, increased time and resource consumption, and potential security risks as personal data is transferred at each verification point, susceptible to interception or hacking. Thus, new-day technology has prompted a reconsideration of traditional KYC methods in favor of more streamlined and secure digital identity verification processes.

Centralized KYC

Central Know Your Customer (CKYC), an initiative established by the Government of India, redefines the KYC process. This centralized repository ensures that once an individual completes the KYC process with a financial entity, be it a bank, mutual fund, or insurance company, there’s no need for redundant processes. CKYC stands out by consolidating all KYC data onto a unified platform.

CKYC serves as a defense against financial fraud, including money laundering and unauthorized fund usage. Its centralized nature enhances oversight and control. Financial institutions reap the benefits of streamlined operations as CKYC eliminates the redundancy of KYC processes. This not only reduces operational costs but also eases the burden of document maintenance. CKYC introduces a revolutionary concept — a single KYC applicable across various financial services. This simplifies the customer experience and accelerates service accessibility.

The Issues In Centralized KYC Systems 

Centralized KYC systems, while designed to enhance identity verification, struggle with significant challenges that impact their effectiveness. A critical analysis of these limitations reveals the need for innovative solutions in financial security. Here are the limitations:

1. Lack of Standardization

Navigating through repetitive KYC processes becomes a hassle for users due to the absence of standardized procedures. Each bank or financial service provider operates with unique specifications, requiring users to adapt to varying requirements during the KYC process. This lack of uniformity not only consumes more time and effort for users but also adds complexity to the overall experience.

2. Enclosed Data Silos

The confined nature of centralized KYC systems creates isolated data silos, hindering Financial Institutions (FIs) from obtaining a comprehensive view of consumer expenses across different platforms. This fragmented data limits FIs’ ability to fully understand customer financial behaviors, resulting in incomplete insights that may impact decision-making and risk assessment.

3. Fraudulent Data Misidentification

The inherent structure of centralized systems makes them susceptible to misidentifying fraudulent data, compromising the accuracy of identity verification processes. The lack of flexibility in adapting to evolving fraud techniques may lead to false positives or negatives, raising concerns about the system’s reliability and effectiveness in detecting fraudulent activities.

4. Customer Tracking Challenges

Seamlessly tracking customers across various platforms poses a substantial issue for centralized KYC systems. The inability to follow customers efficiently across different services and institutions creates gaps in understanding customer behavior and interactions. This limitation may impact the system’s ability to provide a comprehensive and accurate overview of customer activities.

5. Risk of Fake Data Entry

Users pose a risk by entering falsified information into the system, challenging the integrity of the KYC process. The centralized model’s susceptibility to inaccurate data entry raises concerns about the reliability and authenticity of the information collected during the KYC process. Ensuring the accuracy of entered data becomes crucial for maintaining the effectiveness of identity verification.

6. Processing Time Inefficiencies

The centralized model often leads to delays in KYC checks, contributing to inefficient processing times. Complicated processes within the centralized KYC model can result in extended waiting periods for users, potentially impacting their experience and the overall efficiency of the verification system. Simplifying these processes is essential for improving efficiency and enhancing the user experience.

These challenges not only escalate the costs associated with KYC processes but also contribute to an upswing in money laundering instances. 

How Can Blockchain Help In the KYC Process?

Blockchain technology within the banking sector offers innovative models for both intra- and inter-bank verification and update processes.

Blockchain-based KYC Process

1. Intra-Bank Applications

Banks can use blockchain technology to deploy powerful intra-bank applications within their banking groups. This approach drastically reduces the time and effort expended in repetitive effort. When a new service request necessitates additional customer information that is not available in the ledger, the model empowers the bank to seamlessly update the ledger. External agencies then revalidate the updated information, essentially translating into a streamlined re-KYC process.

2. Inter-Bank Applications

In inter-bank applications, participating banks collaborate to establish a consensus on the validation process, building trust and integrity. Bank A takes on the role of the originating bank, conducting the initial KYC verification for a customer. When the customer engages with Bank B for services, Bank B can securely request and receive KYC documents from Bank A through the blockchain platform. This ensures a secure inter-bank document transfer mechanism, enhancing overall process efficiency, standardizing KYC processes, and facilitating near-real-time customer validations.

3. Centralized Blockchain-Based KYC

Another groundbreaking approach involves linking banks to a centralized KYC repository, similar to the existing KYC registry system. In this setup, customer data and documents find a place in the distributed ledger. The bank conducting the KYC process stores all relevant details and generates a unique KYC number. When another bank seeks to perform due diligence on the same customer, it can utilize the unique KYC number to access the central registry and seamlessly download comprehensive customer details.

A Blockchain-based Solution

Blockchain, through these dynamic models, not only addresses the challenges of redundancy and inefficiency in KYC processes but also introduces trust, security, and streamlined collaboration among financial institutions. The adoption of blockchain technology represents a pivotal step toward redefining how banks approach and execute KYC procedures, promising a future of heightened efficiency and enhanced customer experiences.

How Does A KYC Blockchain Application Work?

Adding Blockchain technology to the KYC process brings a big change, making it more efficient and secure. Here are the detailed steps of this transformation:

How blockchain KYC works

Step 1: Building a Secure Profile

Users initiate the KYC process by constructing a profile on the KYC Distributed Ledger Technology (DLT) system. Financial Institutions (FIs) deploy a cutting-edge Blockchain-based KYC platform, streamlining the one-time setup with user identity documents. The uploaded data, stored through various options like a centralized, encrypted server, FIs’ private server, or the DLT platform, becomes accessible for verification purposes.

Step 2: Transactional Transparency with Financial Institutions 1 (FI1)

As users engage in transactions with FI1, they grant access to their profile. FI1 meticulously verifies KYC data, saves a copy on their server, and uploads a ‘Hash function’ on the DLT platform. The KYC digital copies, embedded with a matching Hash Function, ensure data integrity. Any attempt to alter KYC data triggers alerts across the blockchain, maintaining a vigilant network of financial institutions.

Step 3: Seamless Interactions with Financial Institutions 2 (FI2)

When users perform KYC for FI2, access is granted to their profile. FI1’s review of the KYC data and its Hash Function ensures consistency. Matching Hash Functions signify uniformity, while discrepancies prompt FI2 to manually validate KYC documents, ensuring accuracy and reliability.

Adaptive Changes and Smart Contracts

In the cases where users update their documents, smart contracts come into play. As users submit new documents to FI1, smart contracts automatically broadcast changes across the blockchain, employing a new Hash Function. This decentralized approach ensures swift updates, enhancing accessibility for all participating FIs.

Advantages Of Blockchain Technology In The KYC Process

The desire for blockchain adoption among financial firms has been notable for securities cleansing and settlement. However, the decentralized technology extends beyond routine fintech applications. Blockchain’s integration into Know Your Customer (KYC) processes presents an opportunity to improve transparency, collaboration, and efficiency within regulated sectors.
